I have 2 other TENS units but wanted a unit that included EMS and where Pulse width and Rate could be adjusted. This Unit has all that and also has Intensity adjustments from 1 to 100. It is solidly built and comes with good quality electrode pads. Even more amazing is that it comes with the best instruction manual that covers all the different modes in great detail and written in real English….all 35 pages. The other TENS units came with a 2 page sheet with few instructions. Very Satisfied with this unit and Well worth the money. For the price, I was disappointed it did not come with a case like they offer with their less expensive TENS 7000 unit.
I’ll have to look for an after market case to organize all the electrodes, pads and charger.
